anja did some very recent counts:
for HTTP/1.0 we get 1 % 404 reponses
for HTTP/1.1 we get less than 1.5
however, 404 is not the same as broken link. it is a heuristic that should
be (at least) tested by sending requests from different user-agents/sites
just to make sure that ambient things are not resulting in 404.
